1 Claim.

This invention relates to improvements in rubber heels, and the principal purpose of the invention is to provide a heel of rubber, rubber composition or other resilient materials having a removable collar or rim portion which receives most of the wear and which may be readily replaced to renew the margin of the tread surface, at a minimum of expense and without the necessity of nails, screws, or other special fastening elements for the removable collar. A further object of the invention is to equip the removable collar and body parts of the improved heel with cooperative locking elements which hold the collar in place yet permit its ready removal by manual manipulation.

A recommended embodiment of the invention is shown for the purpose of illustration in the accompanying drawing, in which:

Fig. 1 is a bottom View of the improved heel, shown as applied to a shoe bottom;

Fig. 2 is a view of the body portion of the heel with the separable collar removed therefrom; and i Figs. 3 and 4 are sections taken on lines 3-3 and 4-4 of Fig. 1.

The improved heel comprises a body part 24 secured by nails or other fastenings to the heel lift and sole of the shoe; and a collar part 25 surrounding the body part 24. The edge of the body part is undercut where it is engaged by the collar and the interior edge of the collar is beveled correspondingly, so that the two parts are frictionally retained in assembled position. Additional security is afforded by forming a channel 26 beneath an overhanging margin or ledge 2 at the forward edge of the body part 24, and by reducing the thickness of the front bar 28 of the collar 25 so that said bar fits tightly in the channel 26.

This heel is assembled by rst placing the front bar 28 of the collar in the channel 26 of the body part and then stretching the rearward part of the collar over the back of the body part 24; and the collar is removed by first freeing its back part from the body by a lifting and twisting motion.

The collar is applied or removed more easily and quickly and with less strain by grasping the outer edge of the collar with the thumb and fingers and twisting it so that the surfaces consti- Y tuting the beveledjoint between the collar and the body part are engaged or disengaged with a sliding or wiping action. A collar thus engaged will be retained in place during normal Wear of the heel, andthe special interlocking or anchoring elements of the two part heel, which are enregular sizes to fit the complemental body parts.

It will be understood that the size and shape of the improved heel may be varied to suit the size and style of the shoe to which it is to be applied and that the character of the tread surface and other structural details may be varied as desired without departing from the essence of this invention as defined in the appended claim.

I claim:

A rubber heel comprising a body portion adapted to be secured to the heel base of a shoe, and a collar removably attached to the periphery of said body portion, the two parts having complemental surfaces meeting on a line inclined to the tread surface of the heel and extending from said surface toward the central portion of the heel so that the collar is held against displacement by the engagement of said inclined surfaces, the collar having tread surfaces around its side and back portions and a cross bar at the front, said bar being disposed in a plane remote from said tread surface and said body portion having a projecting ledge dening an underlying channel receiving said cross bar, whereby the cross bar is anchored in said channel until displaced therefrom by a forward movement parallel to the tread surface of the heel.
